Onyx Gift Cards is a Grenadian company designed to introduce, market and manage gift cards systems in Grenada for retailers and corporations. We are enthusiastic about the effect and influence we will have on the local market. We intend to expand our systems regionally with a range of product offerings and services.
Gift cards are the preferred way of giving and receiving gifts. They carry a monetary value that can be redeemed for gifts at your favorite store.
Onyx GiftCards are “Open Gift Cards” which means that they can be redeemed at multiple merchant locations. They are standard credit card size, can fit into the average wallet and made of PVC plastic. Onyx GiftCards are Barcoded for security and safety for the consumer and bear a disclaimer at the back.
Onyx Giftcards can be bought with a branded Card backer which is black in colour and is designed to fit the card. There is an area to write a brief message to the recipient as well.
The PayPal sandbox card test process is the practice of running card payments through PayPal's developer sandbox using the sandbox-only card numbers PayPal issues for each test account. Nothing touches the live card networks, and no real cardholder data is involved. The criteria that matter are isolation from production, the type of card data you are permitted to handle, and how closely the sandbox reproduces real approval and decline behavior.
The sandbox is a separate environment with its own accounts, credentials, and API hosts. A card payment you send there is authorized by a simulator, not by an issuing bank. That means you can verify your integration end to end: creating an order, passing card fields to the API, handling the response object, and reacting to errors.
What you cannot learn from the sandbox is real approval rates, real risk decisions, or how a specific bank responds to a specific cardholder. Sandbox test cards are not real cards and cannot be used to move money anywhere.
A test suite that only passes on approval is only half built. PayPal's sandbox supports negative testing, where you deliberately trigger failures to confirm your application surfaces the right message and does not mark an order as paid. Typical cases worth covering include expired card, invalid security code, insufficient funds, and processor decline.
Run each case twice: once through the API and once through the browser checkout, since the two paths often surface errors differently. Log the raw response body during testing. The status field alone rarely tells you enough to debug a failure.
Move to production only after your sandbox suite covers approval, decline, cancellation, refund, and webhook delivery. Then run a small live transaction with a card you control, confirm the settlement and webhook, and refund it. Treat that first live run as a separate test, because sandbox behavior does not predict it.
